3H)-dithione (1) with p-xylylene diisothio-cyanate, reacted with N,N′-dialkyl substituted diamines to give macrocyclic compounds bearing hypervalent sulfur by a ring closure reaction in good yields. These macrocyclic compounds were converted into ring-expanded macrocyclic compounds with release of the hypervalent sulfur by treating with NaBH4 and CF3COOH.

硫酮(1)与p-二
甲苯二异
硫氰酸酯与N,N'-二烷基取代的二胺反应,以良好的收率通过闭环反应得到带有高价
硫的大环化合物。通过用NaBH 4和CF 3 COOH处理,这些大环化合物在释放出高价
硫的情况下转化为扩环的大环化合物。
